1 - INTRODUCTION

Please read carefully the instructions with this symbol before installing and using the instrument.

1.1 - STANDARDS and REGULATIONS

VIP ENERGY2K8 conforms to Directive 73/23/CEE (LVD and 2004/108/CE (EMC .

It has been designed with reference to EN 61010-1, EN 61326 including append. A1/A2/A3, EN 61000-6-2, EN 61000-6-3,

EN 61000-3-2, EN 61000-3-3, EN 61000-3-3/A1, EN 61000-4-2, EN 61000-4-3, EN 61000-4-4, EN 61000-4-5, EN 61000-4-5/A1,

EN 61000-4-6, EN 61000-4-6/A1, EN 61000-4-8, EN 61000-4-8/A1,EN 61000-4-11, EN 61000-4-11/A1.

1.2 - USER SAFETY

In order to preserve these safety conditions and ensure safe operation, the user must observe all instructions and marks

specified in this user manual. All maintenance and repair operations requiring the opening of the instrument must be carried

out only by suitably qualified and authorised personnel. The instrument was shipped from the manufacturing plant in

perfect technical safety conditions.

1.3 - PRELIMINARY INSPECTIONS

Before installation, check that the instrument is in good conditions and was not damaged during transport. Check that the

network voltage and the rated voltage coincide. This instrument does not require an earth connection.

1.4 - PRECAUTIONS IN THE EVENTS OF MALFUNCTIONS

When safe operation is no longer possible, put the instrument out of service and ensure that it cannot be operated

accidentally.

Safe operation cannot be guaranteed in the following circumstances:

· When the instrument appears clearly damaged.

· When the instrument no longer works.

· After long storage in unsuitable conditions.

· After being damaged in transit.

2 - CONNECTION OF THE INSTRUMENT

2.1 - POWER SUPPLY

The power supply connections terminals are located on the rear side and are clearly indicated with the label POWER

SUPPLY. Use cables having a maximum section of 2.5 mm2. Earth connection is not required. Follow the connection

diagram at the beginning of the manual.

2.2 - CONNECTING VOLTAGE MEASUREMENT CABLES

These cables, having a maximum section of 4 mm2, are to be connected to the terminals labelled VOLTAGE INPUT as

indicated in the diagrams at the beginning of the manual.

2.3 - CONNECTING CURRENT MEASUREMENT CABLE

The instrument is able to measure up to 5A only through external C.T. The cables having maximum section of 4 mm2 must

be connected to the terminals labelled CURRENT INPUT as shown in the diagrams at beging of the manual.

Use CT's with 5A secondary. Use cables having a section appropriate to the length of the connection and the rated power

of the CT's used.

Note 1: For safety reasons, never leave the CT secondary open.

Note 2: Important direct connections, without C.T. will damage the inputs.

4.1 SETUP PAGE PROTECTION CODE

By default, the access code to set-up pages is not enabled. To enable it, keep the PAG + SEL keys pressed at the same

time for 30 sec. The display will show the page on which the access code must be entered. [Fig.26].

[Fig. 26]

By means of the SEL + SET keys, every digit can be changed and the code can be entered. The initial

factory code , that must be entered the first time is 000000. Confirm and exit from this page by pressing the

PAG key.

Now a second page (with "COD" blinking , identical to the first one, is displayed:

From this page, the access code can be permanently changed, if wished.

In this case remember or make a safe note of the new code somewhere you can find it later on.

To exit from the second page press the PAG key.

IMPORTANT: After the first access to the password page, the request of the code will become permanent.

From that moment on the code must be always entered to access the set-up page.

Avoid to recall the password page, for test purposes, if the code request is not permanently desired.

4.2  SETUP PAGES

To access SETUP pages press the PAG and the SEL keys at the same time. Press the PAG key to access the next page,

press the SEL key to select a digit or a setting. Use the SET key to adjust it.
